MGD Expression
Manual and assisted meibomian gland expression clears obstructed glands and restores meibum flow. It is both a diagnostic step, grading what the glands yield, and a low-cost first-line treatment for evaporative dry eye.
Key points
- Expression evacuates obstructed meibomian glands so the lipid layer can reform.
- Diagnostic (grading gland yield and meibum quality) and therapeutic in the same visit.
- Performed with forceps, paddles, or expressor instruments, ideally after warming.
- Pairs with warm compresses, thermal devices, and lid hygiene.
What it is
Meibomian gland expression applies firm, controlled pressure across the lid to evacuate meibum from obstructed glands. Diagnostic expression grades how many glands yield and the quality of what comes out, clear oil, cloudy, toothpaste-like, or nothing, which is one of the most useful MGD signs you can record.
How it works
Obstructed glands hold thick, inspissated meibum that will not flow on its own. Warming first softens that meibum; expression then clears the obstruction so the gland can resume secreting a healthy lipid layer. Instruments such as paddles let you express the lid against a firm backstop, and forceps let you express a segment between two surfaces, which is more thorough than cotton-tip pressure alone.
The science
Obstructive meibomian gland dysfunction is the leading cause of evaporative dry eye. Gland expressibility and meibum quality are validated clinical signs of MGD, and relieving obstruction is a core therapeutic target across the staged management of the disease.
Clinical evidence
- The International Workshop on Meibomian Gland Dysfunction (2011) established diagnostic expression and standardized meibum grading as core measures of gland function.
- TFOS DEWS III Management and Therapy (2025) supports a staged approach that includes lid warming and expression for obstructive MGD. American Journal of Ophthalmology
Where it fits and what we carry
Expression is a first-line, low-cost in-office step for obstructive MGD. It complements warm compresses and device-based thermal treatment, and it is easy to repeat at follow-up to track whether the glands are improving. Meibomian gland forceps, paddles, and expressor instruments are on the wholesale platform under equipment.
